Karyotype differentiation in tellin shells (Bivalvia: Tellinidae) [PDF]

open access: yesBMC Genetics, 2017
Background Although Tellinidae is one of the largest and most diverse families of bivalves, its taxonomy is utterly chaotic. This is mainly due to the morphological diversity and homoplasy displayed by their shells and to the scarcity of the molecular ...

Anatomy of Phyllodina persica (Bivalvia: Tellinidae), and its first occurrence in southeastern Brazilian waters [PDF]

open access: yesPapeis Avulsos De Zoologia, 2013
This study presents a detailed anatomy of a rare Western Atlantic tellin, Phyllodina persica, under a comparative scenario. Some characters are shared with other tellinids such as the large hemipalps compared to gills; gills with outer demibranch with a ...

Comparative studies on the histology and ultrastructure of the siphons of two species of Tellinidae (Mollusca: Bivalvia) from Brazil [PDF]

open access: yesZoologia, 2012
Despite the great importance of the siphons for infaunal bivalves, only a few studies have examined their tissues using histology techniques or scanning electron microscopy.

Pacific walrus (Odobenus rosmarus divergens) resource selection in the Northern Bering Sea. [PDF]

open access: yesPLoS ONE, 2014
The Pacific walrus is a large benthivore with an annual range extending across the continental shelves of the Bering and Chukchi Seas. We used a discrete choice model to estimate site selection by adult radio-tagged walruses relative to the availability ...

Some reproductive parameters of populations of Macoma calcarea (Bivalvia, Tellinidae) in the Barents and Pechora Seas [PDF]

open access: yesVestnik MGTU, 2017
Macoma calcarea is a boreal-arctic species widespread in all the northern seas of Russia. Like all bivalve molluscs M. calcarea plays an important role in marine ecosystems.

Different degrees of tolerance to hydrogen sulphide in populations of Macoma balthica (Bivalvia, Tellinidae) [PDF]

open access: yesMarine Ecology - Progress Series, 1997
Populations of the Baltic clam Macoma balthica show different degrees of sulphide tolerance in relation to su lph~de contamination of their habitats. Specimens from sulphidic habitats such a s the Gulf of G d k k (Baltic Proper) and shallo~v waters near the island of Hiddensee (Southern Baltic Sea) have higher survival capaclt~es during sulphide ...

Mitochondrial genomes of the Baltic clam Macoma balthica (Bivalvia: Tellinidae): setting the stage for studying mito-nuclear incompatibilities. [PDF]

open access: yesBMC Evol Biol, 2014
Allopatric divergence across lineages can lead to post-zygotic reproductive isolation upon secondary contact and disrupt coevolution between mitochondrial and nuclear genomes, promoting emergence of genetic incompatibilities. A previous F ST scan on the transcriptome of the Baltic clam Macoma balthica highlighted several genes potentially involved in ...

Significance of body size in sulphide detoxification in the Baltic clam Macoma balthica (Bivalvia, Tellinidae) in the Gulf of Gdansk [PDF]

open access: yesMarine Ecology - Progress Series, 1997
The Baltic clam Macoma balthica, a predominant species of macrofauna in the Gulf of Gda´nsk (Poland), is exposed to high concentrations of hydrogen sulphide at many locations in this bay. When oxygen is available, the species is able to detoxify penetrating sulphide mainly by oxidizing it to non-toxic thiosulphate.
